The paper will include an introduction of dissolvable plug and its development in oil & gas upstreambusiness. Dissolvable plug is a customized tool, and it could be modified by controlling its chemicalcompound to adjust its dissolving rate. In addition, high clearance dissolvable plug is a plug solution withdissolvability originally brought out to overcome the downhole restriction challenge (ID of SSD), namely topass the downhole restriction then to set in the original casing ID. A case study of its application in offshoresqueeze cementing job will be analyzed in this paper, from the plug designing perspective to operationaldata recap to prove its benefits. Conventional plugs will leave the bottom of the plug body downhole afterplugs slip losing integrity during the milling operation, and the remainder leaving downhole will choke thewell production or even block the well, however, dissolvable plug remainders will dissolve itself downhole,which will not have an impact on the production.
